KR8 vs TXT sampler

KR8-0 is a drum machine for live performance. It runs a step sequencer with 16 to 64 steps, four drum kits, per-channel mute and solo, per-channel volume, and a BPM range of 40 to 220. The audio engine runs on a dedicated thread separate from the UI, so the tempo holds regardless of what's happening on screen. Four kits are included. The default kit is synthesis-based: each sound is generated from mathematical waveforms and envelopes computed in real time, with no sample files involved. The three additional kits are sample-based, using recorded drum sounds loaded from audio files on the device. No internet connection is used at any point. No account is required. No data leaves the device.

TXT sampler is a sampler app for iPhone and iPad that lets you play recorded sounds and imported samples on pads, allowing you to create beats using sequences and effects.

By upgrading to the one-time purchase Premium Plan, you will unlock 64 pads across 4 banks, multiple projects, up to 8-bar sequences, long sample support, pad color customization, and WAV file export.
